    LinuxKPI: skbuff: re-add __LP64__ check
    
    Re-add one __LP64__ check for case 2 (36bit upper limit to contigmalloc)
    to fix the build.
    contigmalloc(9) takes a vm_paddr_t argument but on armv7 and some powerpc
    we are still at 32bit there so the constant value would be changed
    from long long to uint (-Wconstant-conversion).
